MACHINE FOR APPLYING BOTTLE-SEALS- Specification of Letters Patent.

Batented Feb. 25, 1908.

Application filed May 1907. Serial No- 3734176- a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State pf NewYork, have invented certain new and Useful Improvements inMachines forApply- Bott le-Seals, of which. the following is a specification.

Thisinvention relates to machines for applying bottle caps andparticularly to a means for ap lying and locking hard metal ca 's to abott e or like vessel, having an annu ar locking shoulder or surfaceadjacent to its mouth, into engagement with which the flange of the capis forced.

The invention relates more particularly 'to the construction of thesealing head,

which it will appear to those skilled in the art, may be employed inmachines of this character, regardless of any special means for loweringthe head or raising the bottle seat, it being immaterial to my inventionwhich of the parts is moved, so long as there'is a movement of one ofthe partsor both of the parts to get the desired and required sealingpressure. I have shown the head mounted on a frame of ordinaryconstruction in which the head is depressed toward the bottle seat, and

- returned to normal position b a s rin or 1n the machine or in themeans for raising and lowering the head, these parts will not bedescribed in detail, save in so far as it is desirable to show a meansfor moving the head.

In the drawings: Figure 1 is a side elevation of the machine; Fig. 2 isa central section of the head with a bottle ea in dotted lines inthe'sealholding cavity of t e plunger; Fig. 3 is a similar view theparts of the mechanismof the head being in about the position they occuy or assume at the moment the flange of the cap is locked into holdingengagement with the locking surface or shoulder of the bottle, the upperportion of a bottle with a cap thereon being shown in section; Fig. 4 isa horizontal section of the plunger taken about on line a-a, Fig. 2 Fig.5 1s a cross section taken about on line b?) Fig. 2, showing the sring-backed pins for temporarily holding t e bottle cap in the plungerpre aratory to the sealing operation.

eferring to the drawings, the numeral 1 designates the machine frame,having ato normal position by a suitable spring 9, as

is usual in machinesof this character. The casing 10 is formed with alower-cylindrical portion 11 and a reduced up er portion 1.2, the lowerortion being provi ed with a bore 13, and t e upper portion with areduced bore 14.

The plunger is designated by the numeral 15. It is made with a number ofradial recesses 16 cut in from its eri hery in which are arrangedpivoted sea loc ing levers17, preferably six in number. These leversareeach provided with short inwardly extending indenting points 18, whichare simultaneously projected into the seal holding cavity 18 of theplunger to pinch the flange of the cap at intervals under the shoulderon the bottle, when the sealing pressure has been a plied and the sealseated. Intersecting t ese recesses 16 area corresponding number ofradially arranged a ertures 19, that pass from the periphery of t elunger to the central opening 20 therein. T e upper arms of theseallocking levers extend into the recesses 19, where their inner facesare enga ed by springs 21, whose inner ends are seate in cups 22, formedwith rounding or cam surfaces 23, which are engaged by the bevel or camsurface 24 of a rod 25. This rod is held fast at its upper end within ascrew cap 26, and has no vertical movement in the operation of the headparts, although as will a pear later, the rod-may be adjusted vertica lyto vary the point at which its bevel willengage the cu s 22. Theconnection betweenthe rod an cap is a threaded one, whereby said rod maybe adjusted up or down to vary the point at which thecam surface 24thereon will engage the rounded ends or cam surfaces 23 of the caps 22.The adjustment is maintained by means. of a lock nut 27, provided .withspanner holes 28 by which it may be conveniently turned on the threadedportion \29 of the rod. Interposed between the nut 27 and the u per edgeof a reduced extension 30 of the pl imger is the sealing spring 31-,

ing head as especially ada connected to the casing by threads 34 andobviouslyreadily removable when it is desired to have access to theplunger arts, the

= annular locking surface'or shoulder adjacent -to their mouths, itwillbe understood that" the heads would be equally adapted for applyingcaps or covers to vessels other than ottles, such as glass jars, cans,'etc.,'it being obviously only necessary to vary the dimensealing headnon-rotata Y yielding seal applying plunger in said head sions of thehead art to accommodate them to such additiona uses.
